4. Jupiter. Jupiter is the fifth and largest planet in our solar system. This gas giant has a thick atmosphere and a dark, barely-visible ring composed of dust from nearby meteoroids. Its most prominent features are bands across its latitudes and a great red spot (which is a storm). Jupiter is the fifth and largest planet in our solar system. This gas giant has a thick atmosphere and a dark, barely-visible ring composed of dust from nearby meteoroids. Its most prominent features are bands across its latitudes and a great red spot (which is a storm). Jupiter is a gaseous planet; it does not have a solid surface like the Earth does (but probably has a solid, rocky core 10 to 15 times the mass of the Earth). When we look at Jupiter, we are seeing icy clouds of gases moving at high speeds in the atmosphere. The surface temperature of the highest clouds is approximately -153°C. Jupiter's atmosphere is composed of about 90% hydrogen and 10 % helium.

5. Jupiter has four large moons and dozens of smaller ones (there are about 60 known moons so far). Galileo first discovered the four largest moons of Jupiter, Io, Europa, Ganymede, and Callisto in 1610.

6. Saturn  Saturn is the sixth planet from the sun in our solar system. It is the second-largest planet in our solar system.  Each day on Saturn takes 10.2 Earth hours. A year on Saturn takes 29.46 Earth years; it takes 29.46 Earth years for Saturn to orbit the sun once.  Saturn has dozens of moons (33 discovered as of August, 2004). It has 18 named moons. including Titan (the largest), Rhea, Iapetus, Dione, Tethys, Enceladus, Mimas, Hyperion, Phoebe, Janus, Epimetheus, Pandora, Prometheus, Helene, Telesto, Atlas, Calypso, and Pan (the smallest named moon of Saturn). At least a dozen others have been noted (but not named yet).  Saturn Continued

7. Saturn's bright rings are made of ice chunks (and some rocks) that range in size from the size of a fingernail to the size of a car. Although the rings are extremely wide (almost 185,000 miles = 300,000 km in diameter), they are very thin (about 0.6 miles = 1 km thick).

8. Uranus Uranus is the seventh planet from the sun in our solar system. This huge, icy planet is covered with clouds and is encircled by a belt of 11 rings and 22 known moons. Uranus' blue color is caused by the methane gas in its atmosphere. Uranus is the seventh planet from the sun in our solar system. This huge, icy planet is covered with clouds and is encircled by a belt of 11 rings and 22 known moons. Uranus' blue color is caused by the methane gas in its atmosphere. Uranus is tilted on its axis at an angle of 97.9%. It rotates from top to bottom instead of side to side like other planets. Astronomers believe that Uranus was hit by another object that knocked it on its side, billions of years ago. Uranus is tilted on its axis at an angle of 97.9%.

10. Neptune Neptune is the eighth planet from the sun in our solar system. This giant, frigid planet has a hazy atmosphere and strong winds. This gas giant is orbited by eight moons and narrow rings arranged in clumps. Neptune’s color is caused by methane gas in its atmosphere. Average temperature is -225 C Neptune is the eighth planet from the sun in our solar system. This giant, frigid planet has a hazy atmosphere and strong winds.

11. Astronomers have discovered eight moons revolving around Neptune. Neptune’s largest moon is named Triton. Triton’s south pole is covered with ice and dark material erupts from underneath of it.

12. Pluto Pluto is a dwarf planet that usually orbits past the orbit of Neptune. It was classified as a dwarf planet in 2006; before that it was considered to be a planet, the smallest planet in our solar system. Pluto is smaller than a lot of the other planets' moons, including our moon. Pluto is the only "planet" in our solar system that has not been visited by our spacecraft yet. We only have blurry pictures of its surface; even the Hubble Space Telescope orbiting the Earth can only get grainy photos because Pluto is so far from us. In 2015, a spacecraft called New Horizons (launched by NASA in 2006) will visit Pluto. Pluto is a dwarf planet that usually orbits past the orbit of Neptune.
